“…Typical glow discharge or DBD by the ferroelectric effect have been highlighted by different studies [1]- [3], often using the Rosen-type transformer because of its high voltage ratio. However, the growing field of these applications is partially blocked because there is insufficient knowledge of the nonlinear electromechanical behavior of Rosen-type transformers inherent to their operating conditions.…”

“…The last can be subdivided in ozone generation by dielectric barrier discharge (DBD) in oxygen [46] and air [90], by surface dielectric barrier discharge (SDBD) [91,92] or by corona discharges in air [93], oxygen, and carbon dioxide [94]. However, the RPT driven discharges are also used for production of ozone [29,30], both in air and in oxygen [95,96]. The PCPG is generating ozone in different oxygen containing environments.…”

“…The microdischarges produced in the narrow gap between the high-voltage side of the RPT, and the dielectric barrier was observed optically through the transparent ITO-electrode [181]. Similar discharge configurations are used for ozone production [95]. The up-scaling of the ozone production rate was achieved by a parallel connection of six RPT devices [29].…”

The piezoelectric direct discharge (PDD) is a comparatively new type of atmospheric pressure gaseous discharge for production of cold plasma. The generation of such discharge is possible using the piezoelectric cold plasma generator (PCPG) which comprises the resonant piezoelectric transformer (RPT) with voltage transformation ratio of more than 1000, allowing for reaching the output voltage >10 kV at low input voltage, typically below 25 V. As ionization gas for the PDD, either air or various gas mixtures are used. Despite some similarities with corona discharge and dielectric barrier discharge, the ignition of micro-discharges directly at the ceramic surface makes PDD unique in its physics and application potential. The PDD is used directly, in open discharge structures, mainly for treatment of electrically nonconducting surfaces. It is also applied as a plasma bridge to bias different excitation electrodes, applicable for a broad range of substrate materials. In this review, the most important architectures of the PDD based discharges are presented. The operation principle, the main operational characteristics and the example applications, exploiting the specific properties of the discharge configurations, are discussed. Due to the moderate power achievable by PCPG, of typically less than 10 W, the focus of this review is on applications involving thermally sensitive materials, including food, organic tissues, and liquids.

“…The piezoelectric [1] transformers (PT) [2] of Rosen type [3] are broadly used as a high-voltage source for power electronics. [4,5] The earlier generations of PTs allowed for the ignition of low-pressure gaseous discharges, such as neon lamps, [6] cold cathode fluorescent lamps (CCFL), [7,8] silent discharge exciters in nitrogen, [9] oxygen-containing gas mixtures for ozone generation, [10][11][12] ionic wind generators, [13][14][15] or plasma for thrusters. [16] The resonantly driven PTs [17] with multilayer structure [18] reached transformation rates sufficient for sustaining an atmospheric pressure discharge in noble gases.…”

The piezoelectric direct discharge sustained using a high-performance piezoelectric transformer (PT) with a voltage transformation ratio of >1,000 was used for the generation of an atmospheric pressure plasma jet (APPJ). The ionization gases used are ambient air and compressed dry air. The APPJ was characterized using capacitive probe measurement, ozone concentration measurement, and activation area determination. The activation experiments were conducted on a highdensity polyethylene. The activation area was visualized using pure formamide test ink (58 mN/m) and captured by a digital camera. The influence of gas flow, PT power, and the distance between the PT and the substrate were investigated.
